Our company mainly produces Ф20mm—Ф130mm low,middle,high chrome alloy casting iron ball. Chrome alloy casting iron ball are widely used in cement, building materials, metal mining, coal slurry thermal power, ceramic coating, ultrafine powder preparation of magnetic materials and other industries and further processing.
Low chrome casting steel ball
Chrome Concentration is 1-3%, hardness ≥ HRC 45, this steel ball is called low chrome grinding balls, which is made by smelting in intermediate frequency electric furnace, metal mould or sand casting process. It applies to metallurgic mines and slag industries where no high grinding accuracy or wearability is required.
